فارسیDouble-glazed pipeline cryogenic jacket
What is a vacuum jacket?
In the first part, the double-glazed tube is made using a MLI super-thermal insulation, with safety equipment, flow valves and flexible connections. In the second part, the insulation of this pipe and its type of coating are of great importance. In general, due to the high level of technical knowledge, special type of design, insulation, high vacuum level and temperature variation, this equipment can be considered as a small cryogenic reservoir. Vacuum sweatshirts for liquid oxygen transfer, liquid nitrogen (liquid nitrogen ) And LNG. Due to the use of this equipment in the transmission of cryogenic fluids, the temperature is very low. For example, We want to transfer the liquid nitrogen produced by the box box to the storage tank. If we use a single-walled tube or a non-standard vacuum jacket, this fluid will be heated by heat (196 ° C) and evaporates to a high degree. This makes the reservoir pressure higher, which is not desirable. The experienced pilot and experienced designer of all kinds of vacuum sweatshops has been able to offer good service to industrial and non-industrial complexes.
Vaporizers
What is a Vaporizer or Heat Exchanger?
Viprazers or heat exchangers are equipments that, without the need for electricity, water, etc., can only convert gas from gas to gas through the use of air flow, such as nitrogen, oxygen, argon and … Liquid to gas. The converter is based on the ambient temperature difference with the fluid temperature, such that the liquid passes through the tube connected to the fin and changes the liquid state to the gas. A specific type of blade design, blade length and number of blades and impeller There are a few important points to consider in choosing a vaporizer: 1) the amount of liquid inlet and the amount of gas flowing; 2) the type of fluid 3) the operating time 4) the pressure of the 5-k The lowest ambient temperature at the site of the installation of the pilot company in the sky, with the ability and experience of designing various types of brackets, is in the service of our beloved industry.
Repair of cryogenic reservoir
Due to the complex and double glazing of the cryogenic reservoirs, the repair of this reservoir is very specialized work. Without access to the internal reservoir and the two-wall pipes, this is far more difficult. In the repair of the reservoir should be the year of construction of the reservoir and the duration of the operation Special attention is paid to the cost of repairing cryogenic reservoirs is often higher than the actual cost of the tank. To repair the cryogenic reservoir, the following points should be considered: 1 year of construction of the tank 2 – the actual value of the tank 3 – the cost of repairs 4 – the reason for repair (Do It can be continued with this problem. 5. Fault detection in the internal or external reservoir
External tank:
Using different tests, first, it should be noted that the problem or leakage of the internal reservoir or the outer reservoir is determined. 1. If the problem is in the external reservoir, you must first specify the exact point and use the conventional methods to identify and The tests are repeated again. The result of the work is determined after filling and emptying the reservoir several times and measuring the volume of the vacuum.
Demolition of vacuum or insulation :
If the reservoir has disappeared, the reservoir must first be placed under a high vacuum to determine the leakage rate. If there is no leakage, the volume of the reservoir is monitored for a long time in both dry and liquid conditions. The charge of perlite in If the reservoir is perlite insulating, it can also be fruitful.
Internal tank :
The most difficult repair of the cryogenic reservoir is when the fault is internal to the steel tank. It is easier to work in the reservoir in which the local area is to enter. Otherwise, the external reservoir and internal reservoir must be separated, so that repairs It should be done on the internal reservoir. These repairs should be carried out in the companies with high expertise, because of this type of design of the reservoirs.
Pipes and fittings :
The failure of the pipe and fittings in the fixed and standing tanks is less likely to occur, but it is more likely to be carried out in the tanks. In this case, tests must be carried out on the reservoir to identify the defect and, using conventional methods, defect on the side To make
It should be noted that the company with the ability and experience of the construction and design of reservoirs from 1 to 220 tons has the ability to build any type of reservoir with any pressure demand. The time of construction of cryogenic tanks with a capacity less than 30 tons in about (4 months) And the duration of the cryogenic repository is more than 30 (about 6 to 8 months).
